It's that time of year when homes have their highest energy demand of the year. Heating accounts for 34% of all annual utility usage and is part of what makes an average home twice the emitter of carbon dioxide emissions as a vehicle. Here is a way to reduce the demand for expensive space heating. Check the ducts. To ensure that as much warm air as possible is delivered through your central system, check the ductwork and wrap any leaks with duct mastic. Distribution losses (what's lost while air is transported from your furnace through ductwork to the vents) often amounts to 30%. So, sealing ductwork could increase efficiency and the warm air you receive considerably ... keeping you warmer and making your furnace work less. Need a duct evaluation?
